The d&b audiotechnik B4 is a compact cardioid subwoofer designed for tight, controlled low-frequency reinforcement on professional stages and in touring rigs. Its hybrid design couples a front-facing 15-inch driver with a rear 12-inch driver to deliver focused bass energy to the audience while significantly reducing spill on stage and behind the cabinet. This ensures improved clarity and gain before feedback in challenging environments. Offering a frequency response of 40–150 Hz (40–100 Hz in 100 Hz mode) and maximum output up to 131 dB SPL, the B4 provides punchy, musical low end with excellent pattern control. The cabinet features neodymium, long-excursion drivers, a nominal impedance of 6 ohms, and power handling of 500 W RMS / 2000 W peak (10 ms). Connectivity is via two NLT4 (F/M) sockets wired 2+ / 2– for streamlined system integration. Measuring 476 × 580 × 700 mm (H × W × D) and weighing 44 kg, with an approximate depth of 800 mm including castors, it’s built for efficient transport and deployment. Ideal for live sound, theatre, and corporate events where bass precision matters.
